we shall cast stones at them

For the prophet will cite the actual course of events as proof that he was right from the very beginning.

So let us pick up the stones and pebbles by the roadsides of our minds and throw them at these false prohets. Let us build a trench of fire and hang them at the stake to burn. Purge not only their false prophesies, but their very being from the existence of our minds, because their triumph is our end. Hunt each one of them down, bring them to face the fury of flames, and engulf them in it, once and for all.
